Vergara, 40, is naturally a blonde, but has dyed her hair dark in recent years. "I'm a natural blonde, but when I started acting, I would go to auditions, and they didn't know where to put me because I was voluptuous and had the accent — but I had blond hair," she told Self magazine in 2010. "The moment I dyed my hair dark, it was, 'Oh, she's the hot Latin girl.' "
